An electronic apparatus comprising an environment sensing device, a display, a touch sensing device, and a processing module comprising a main controller and a sub-controller is disclosed. The main controller performs a predetermined function based a touch input. The sub-controller computes a tilt angle of the electronic apparatus, and activates the touch sensing device without turning on the display if the tilt angle falls in a predetermined angle range, while the main controller is in the sleep mode. The processing module performs following steps when the display is off: determining the touch input is valid or invalid; keeping the display off if the touch input is invalid. The sub-controller wakes and activates the main controller to turn on the display and to control the electronic apparatus to perform the predetermined function according to a gesture formed by the touch input if the touch input is valid.

Touch input determining method which can determine if the touch input is valid or not valid and electronic apparatus applying the method

A touch input determining method applied to an electronic apparatus with a touch sensing device, which comprises: (a) determining a size for a region of the touch sensing device that an object provides at least one touch input to; (b) if the size is larger than or equals to a first predetermined value, not determining the touch input is a valid touch input; and (c) if the size is smaller than or equals to a second predetermined value, not determining the touch input is a valid touch input, wherein the second predetermined value is smaller than the first predetermined value.
